Sync customers, orders, and newsletter signups to Omnisend — power email & SMS automations with real store data.

About Omnisend

Omnisend is an email & SMS marketing automation platform. Connect your Omnisend account and Cartly automatically pushes your store data: newsletter signups (as subscribed contacts) and order lifecycle events — "placed order" on every paid order and "order fulfilled" on shipment. These fire Omnisend's prebuilt order-confirmation, shipping-confirmation, and post-purchase automations.

## Setup

1. In Omnisend (Store settings → Integrations & API → API keys), create/copy an API key.

2. In Cartly, open Settings → Integrations → Omnisend, paste the key, and click Test Connection.

3. Optionally set a tag applied to synced contacts, and enable the sync toggles.
